python zlib compress decompress

compress:

新建compress.py文件 内容如下：

import zlib

s = open('./sourcedata.txt', 'r').read()

z = zlib.compress(s)

with open('./compressdata.txt', 'w') as f:

f.write(z)

用法 ： python compress.py

这样就实现了压缩sourcedata.txt的内容  压缩后的内容写入compressdata.txt

decompress:

openssl zlib -d < ./compressdata.txt > decompressdata.txt 

把压缩文件compressdata.txt 解压到decompressdata.txt 中
